Abstract

A process for preparing blazed hologram suitable for mass-production which comprises fabricating a glass or metal plate (5) having a surface of serrated cross section, disposing the glass or metal plate in an injection mold (6) to allow the surface of serrated cross section to constitute an inner surface of the mold, injecting an acrylic resin in molten form into the mold under a specific molding pressure, and removing a molded acrylic resin (10) from the glass plate or metal plate to obtain an acrylic blazed hologram.
